Any one of them, though I favor the 3 for its AF, the controls, and the price. I had been looking for years, and finally just got one. For me, it is a special-purpose camera, as most of the time I use my oldies but goodies. However, I could not be happier with the 3, for what I wanted it for.

Next on the list for me would be the 1N.

I do not like the 1 at all, unless used with manual focus...and at that point, why use it at all?
